2) The power supply MOS FET Q101 carries out the ON/OFF operation of the control unit, by means of

U101 KA3842A. KA3842A is a PWM (pulse width modulation) IC chip, with 16 V starting voltage and

10 V cut-off voltage.

The following list shows the pin layout of KA3842A pulse width modulation IC chip.

Pin 1:

Feedback

Pin 2: Compensation

Pin 3:

Current sensor

Pin 4: Oscillator

Pin 5:

Ground (GND)

Pin 6: Pulse output

Pin 7:

VCC

Pin 8: VREF (5.1 V)

3) Overcurrent protection

R111 is a sensor resistor, and it has the function of increasing the current of this loop when the

output of the secondary side is either in the overloaded state or is insufficient.

Since the current passing through the R111 sensor resistor has voltage dropping effect, the opera-

tion of the output pulse is stopped when a voltage lower than 1 Volt is detected at the pin number 3

of the KA3842A 3chip, and the switch of the power supply MOS FET is kept in the “break” state

until the VCC voltage is charged up to 16 Volts, and the operation of U101 KA3842A is resumed.

When it is not clearly known whether there is voltage shortage or not, however, this circuit repeats

the ON/OFF switching, and the power supply LED lights up.

4) Starting circuit

The resistor R164 and R168 and the transistor Q112 and diode D107 and resistor R165, R149 and

zener diode ZD105 are for the starting operation. When the circuit starts its operation, the power

supply transformer T101 supplies the auxiliary 12 Volt power to the control IC chip U101 via pins 6

and 7 of the winding transformer T101.

5) Synchronization circuit

The synchronization signal is induced from the fly-back transformer (FBT), and carries out the

synchronization with the power supply frequency. The frequency range is from 31 kHz to 61 kHz,

and the component elements of the synchronization circuit are C114, R116, D109, R115 and R117.

6) Feedback circuit

The feedback circuit loop induces the 12 V voltage through the pin 6 and the pin 7 of the power

supply transformer. That voltage is connected with the pin 3 of the IC chip U101 by passing

through D108, C113 and passing next through R122, VR101, R120 and R190. This is a regular

loop.

7) Snubber circuit

The snubber circuit has the function of clamping the ON/OFF spikes of the power supply MOS-FET,

and its component elements D105, C106, R106 make up a snubber that turns OFF the power

supply MOS-FET.

8) Secondary rectifier and smoothing rectifier

The secondary rectifier is a harmonic rectifier consisting of D111, C124 and R128, and it works as a

snubber circuit as well. The capacitors C120 and C138 are the smoothing rectifier working on the

45 Volt DC output. There are also other DC outputs, such as 80 Volt (D110), 13.5 Volt (D112) and

6.3 Volt (D113).
